Leonardo da Vinci once said, "Science is a general, and practice is a soldier." Practice is the channel to test truth, and practice is the only way to success. True knowledge comes from practice.

"Practice is the criterion for testing truth." As early as in the evolution of China Revolution, the importance of practice has been proved.

If you don't practice, whatever you do, you will be instigated and pushed around like a pony crossing the river. As the saying goes, "Only you know whether the shoes fit or not. Similarly, being a man and doing things need a criterion, and this criterion is practice.

In ancient times, there was Shang Yang's "Yuanmenzhu", but why did that person get 50 taels of gold? That's precisely because he is not just talking like other onlookers. He dared to try and finally got a good reward. Most importantly, his actions proved that the Qin Dynasty kept its word, and the policy was enlightened under Shang Yang's political reform.

If everyone is indecisive and doesn't trust Shang Yang at all, then no one can know the honest attitude of the Qin government, let alone trust or criticize it. Therefore, whether it is ancient or modern, society needs some people who dare to stand up and practice to measure the pros and cons.

Practice is conducive to innovation, and practice is the road to innovation. "Genius is one percent inspiration and ninety-nine percent diligence."

On the road invented by Edison, diligence refers to experiments all night, day and night. Just because of the invention of electric light, he experienced 1600 failed experiments. It was these failed experiments that finally laid the foundation for his success.
